Do you pee in the shower? According to mathematics, you should be.

You should be peeing in your shower, not just for the liberating and the rebellious adrenaline rush that you may or may not get from it, but because you could save the planet, just a little bit, by doing so.

Every single time you pee, you have to flush the toilet.

Whereas those foul smelly poops do need considerable amounts of water to send them off to the mysterious aquatic underworld below, urine barely needs any encouragement once the flushing begins.

Although many toilet flushes can be stopped part of the way through their noisy waterfalls, most can’t, and that’s wasting a heck of a lot of water.

An average flush for a modern, Western-style toilet uses 6 liters of water, and the average adult pees about seven times every 24 hours.

That means that each day of weeing takes 42 liters of toilet water to flush away.

There are 319 million people in the US, so assuming they all pee the same, which they don’t, but we’re making broadly accurate assumptions here, that’s about 4.9 trillion liters of water flushed away in the name of urine every 365 days.

Say that this means that you only pee in a toilet six, not seven times, per day.

Extrapolating this to the entire US population, that’s 699 billion liters of water saved.

Partly thanks to man-made climate change, and partly thanks to the inefficient use of water resources, water supplies around the world are running incredibly low.
